Kleer has teamed with the Korean company DigiFi to create Opera, a cordless headset that wraps around your head and over your ears with an iPod adapter. They claim it has CD-quality audio with up to 10 hours of continuous play. The Opera also has multi-point Listen in technology so that four people, if they also have a set of the buds, can listen to the same audio stream. We would love to find a set of earbuds that are really comfortable and have no cords to choke on but might think twice at a MSRP of $98.00.
